Image Resizing (DePo Masthead)

I have uploaded images to the media library. However, when I insert them into a post they automatically resize to what appears to medium size. I want them to remain full size. Anyone have any thoughts why this is happening and how to stop it? Thanks for the help.

I cannot help you with CSS. There is no Staff support for CSS editing and precious little Volunteer support. You will have to be patient while you wait for a Volunteer who wants to tackle this. I will flag the thread so it does get moved to the CSS editing forum for you. Good luck. :)
